To all whom it mag concei e: r

Be. it known thatI, Mfifiiinw R. FRE -a citizen of the United States, residing at Kansas City, in, the county of Jackson and State of Missouri, have invented new and useful Improvements in Electric Water- Purifi'ers, of which; the following is a specification. f

The purpose of the present invention is to devise means for purifying and sterilizing water for drinking and domestic purposes' generally.

The invention has for itsobj'ect to supply means for the purification of water both by filtering and. by electrolysis the latter serving to destroy all living organisms and bacilli whereasthe filtering removes all foreign matter from the water. I

The invention conslsts of a receptacle subdiuided; into a plurality ofchambers or co1n-- partments, one of said chambers containing electrodes by means of which purification by electrolysis is e1i'ected electrically, and certain other compartments or chambers, con-- taining filtering material for purifying the water Icy-physical action in the, manner well understood. i c

The invention consists *of the novel featiu cs details'of construction and combinations of parts which hereinafter will be more particularly set forth-illustrated in the drawings hereto attached and finally claimed.

Referring to the, drawings forming a part: .ot the specification, Figure 1 is a vertical purifying appar- Fig. 2- is a centralscction of a water .ratus embodying the invention. horizontal section thereof on the line 22 of Fig. l.,- the inflow and the outflow pipes being omitted. v

The receptacle l'may be of any construction and capacity depending upon the special use and adaptation of theapparatus. A partition 2 subdivides the receptacle into vertical compartments or. chamberslin each of which filtering material'is placed. Perforatd plates 3 are supported in the chamhers or compartments formed by the partition 2 and sustain the filtering material. A-

plate 4 closes the upper ends of said chamers or compartments and is Supported upon the partition 2 and upon the upper end of the receptacle 1.. This plate 4 1S likewise perforated to provide for the water during the (purifying process. The

a free passage of lates 3 are supports on lugs 5 extended inward from the partition 2 and the walls of the "receptacle 1. The partition 2 extendsto the bottom 6 of the receptacleand is jointed at its vertical edges with inner walls of the receptacle at diametrically opposite points. The supporting plates 3 are elevated a distance from the bottomd of the receptacle and the space between the bottom 6 andthe said plates 3 is divided by the partition 2 into chambers 7 and 8 the latter having connection with the inlet and the former with the outlet. The inflow ipe 9 may connect with any source of supply for the water to be purified and connects with a boss or coupling provided at a side of the rece tacle opposite the chamber 8. A faucet v nects with a boss or con ing provided upon a side of the receptacle in communication with the, chamber 7.

The chamber I1 formed upon one side of the partition 2 is-adapted to receive fibrous filtering material of any nature such as fresh 10- or drawing off the jlaurifiedwater confiltering pulp, mineral wool'charcoal or the so in the opcra-tio'noi the apparatus the water in its passage through the appliance is subjectcd toelectrolysis which insures destruction of organisms and efiects sterilization and an elimination of bacilli of every nature. The electrodes 14 have adjustable connection with the structure .inclosing the chamber 13 so as to 'very the effects as may be required.

The electrodes may be of any conducting material best adapted for the y 4 purpose.

The chamber 13 is inclosed by means of a cap 15 which is threaded to the upper end of the receptacle 1 and is formed with an innor shoulder to overlap the perforated plate 4 and retain the latter in place. A dome 16- surmonnts the cap 15 and constitutes a reservoir to contain a quantity of water. The dome 16 is centrally disposed hence the water in its circulation is compelled to pass the electrodes twice, once in its upward ascent inthe dome and secondly by its descent of said dome into the chamber 12 preliminarily in its passage through the faucet 10. The dome 16 and tion as may be found most desirable according to the size or capacity of the purifying ap aratus.

ach electrode is supported by means of a holder the latter consisting of a sleeve 17 set in the rim of the cap and receiving the electrode which is ad'ustable therein, the electrode being insertible in or removable i chamberSthence'passesupwardly through the through the outer end of the sleeve without necessitating the removal of the latter from the ca A hollow stud 18 is provided at one' si e of the sleeve 17 and islinternally threaded to receive a set screw 19 by means of which the electric wire 20 is retained in place, the end-of said wire being inserted in the opening extending laterally through the stud and intersecting with the opening there0f.- A bushing 21 of insulating material is interposed between each of the sleeves 17 and the rim of the cap'to prevent short circuiting of the electrodes 14.

In the practical operation of the apparatus it being assumed that the parts are assembled substantially in the manner illustrated, the water to be purified enters the filtering material in the ehamberll and enters the electrolyzing chamber 13 in which it is subjected to the action of an electric current passing between the electrodes 14. The

water passes upward from the electrolyzing chamber 13 into the dome or reservoir 16 thence downward again into the electrolyzing chamber and through the filtering material into the chamber 12 into the chamber 7 and when the faucet 10 is open the purified water is drawn ofl' therethrough from the chamber 7.

From the fore oing description, taken in connection with t e accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skil ed in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consirler to the best embodiment thereof, I

desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto. cap 15 mav be of integral or separate forma- Claims.

ivided by means of a vertica partition into chambers, perforated lates supported within the lower portions of said chambers-a short distance above the bottom of the receptacle, fibrous filtering material in one of said chambers trolyzing chamber and a reservoir surmountmg said cap and in communication with the electrolyzing chamber.

2. The herein described water purifier com rising a receptacle, a vertical artition sub ividing. the receptacle into cham ers, the one having an inlet at its lower end and the other an outlet, perforated plates supported within said'chambers' a short distance above the bottom of the receptacle, fibrous filtering material in one of said chambers granular filtering material in the other ch perforated plate closing the up er ends of 1 1. An apparatus for purifyin water the same comprising a receptacle su amber, a
